The key for me wasn't to invest in the 'best place' but to know a market so well that a deal jumps off the page when it appears.

A sellers market in general.

Unless you have $5 - 10k MONTHLY to spend on marketing this is what you need to do to have any chance for success with wholesaling.  

There are really great REI opportunities in different markets - markets in the Midwest and Southeast of the country are particularly lucrative - where not only are the purchase prices reasonable for most RE investors, but the homes are turnkey (new builds or completely rehabbed homes, tenant ready, systems 10 years of life remaining on them, property management teams in place) with appreciating home value AND appreciating rent.

While Colorado's market can be challenging due to high prices, exploring suburbs like Colorado Springs or Pueblo, or even considering out-of-state markets in the Midwest or Southeast, can open up better cash flow opportunities.

Connecting with an investor-friendly agent in your chosen market is also a good idea.

In fact, just finished one that I have yet to put on the market. 

Quote from @Michael Florkowski: I really like this approach.

But if you're willing to take a tiny leap of faith, I think the returns are solid, the diligence and the integrity are there, and the states/markets/submarkets and the asset class are thumbs-up.

When the next down market comes, it’s going to be brutal.
